JOHN m. m: VILBISS, or monns'ro, CALIFORNIA E can run'cn Application filed January 5, 1932. Serial No. 584,853.

My present invention has reference to a device for punching milk containing cans or the like, to provide such cans with both an air inlet or vent opening and an outlet for the contents thereof, and the primary object of the invention is the provision of a device for this purpose which is of an extremely simple construction and which may be cheaply manufactured and marketed, and which will operate to effectively puncture cans of difi'erent heights.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawing:

Figure l is a side elevation of the improvement. I

Figure 2 is a front elevation thereof.

Figure 3 is a top plan view thereof.

Figure 4 is a sectional view approximately on the line 44 of Figure 1.

Figure 5 is a sectional view approxlmately on the line 5-5 of Figure 1.

My improvement is wholly constructed of comparatively thin but strong metal, the same including a base 1 upon which cans 2 of dilferent sizes and heights are to rest.

There is secured on the base, adjacent one end thereof, by rivets or like elements metal straps 3. The straps, in a line w1th the longitudinal center of the base 1, are bent upwardly against each other to prov1de th e standard 3 of the improvement, and it is against the inner face of this standard that r the can 2 contacts.

Pivotally secured, as at 4, to the upper end of the standard there is the handle member 5 of the improvement. The handle is made from a single piece of metal having its outer end widened, its upper side rounded and provided with side flanges through which i the pivot 4 passes. There is pivotally secured between the sides of the handle 5 an arched depending link 6, and this link in turn is pivoted between the sides'of what I will term a plunger 7 The plunger head 7 is formed from a single piece of metal which is centrally bent upon itself to space the sides thereof so that the bent portion connecting the sides may contact with the outer edg e'of the standard 3' and the sides proper contact with the sides of the'standard. There. i

'is, however, a space between the standard 3 and this portion of the plunger. to avoid friction, and inward of the pivotvthat con- 7 nects the link 6 to the plunger there is journaled between the sides of the said plunger a shaft 8 for an anti-friction roller Qthat contacts with the'standard 3. I Secured between the sides, to the lower and straight edge of the plunger 7 there is a plate 9, and this plate is provided, adjacent to'its corners, with depending sharpened eX- tensions 10, respectively, the same being the nature of pointed knives;

By raising the handle. 5 the plunger, through the medium of the link 6, will be readily raised on the standard 2 to permit various sizes and especially various heights of cans2 being arranged upon the base 1. 7 Y

A downward movement of the handle 5 will impart a like movement to the plunger to cause the knives 10 to contact with and enter. the top of the can and thus provide the can,

with an air inlet and ventilator and with a7'5' pouring opening. The plate 9 may be provided with more than two outer knives or penetrating elements 10 so that the can will 7 thus be punctured in three places to afford; 1 i

an air vent and two pouring openings or '80 outlets. I I i The simplicity and advantages of the construction will, it is thought, he understood and appreciated by those skilledin the art to which this invention relates so that further detaileddescription will not be required.

Having described the invention, I claim:

A can puncturing. device I constructed wholly of metal to include a fiat base, straps,

arranged in lapping relation and provided i with offset ends which are secured to the base and affording a standard, a rolled handle having its sides and oneof its ends pivotally secured to the standard, a plunger formed, from a sheet of metal which is centrally bent upon itself to provide spaced sides, and which plunger is arranged for slidable movement on the standard, anti-friction means between the sides of the plunger to contact with one edge of the standard, anv archedj link having one end pivoted to the handle and its other end. pivoted between the sides of the plunger adjacent said anti-friction means, a plate fixed between the sides of the I 5 plunger having one of its edges in contact 1 with the standard and having itsrends integrally formed with depending pointed and sharpened elements. 7 In testimony whereof I aflix m signature.
